DRAG-SAW.

SPECIFICATION forming part of Letters Patent No. 43 7,532, dated September 30, 1890.

Application filed October 24, 1889. Serial No. 328,004. (No model.)

. clare the following to be a full, clear, and

exact description of the invention, such as will 'enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked hereon, which form a part of this specificaion.

This invention relates to drag-saws and aims to improve the general construction of` the same, whereby the machine will be compact, comparatively light, durable, and etticient.

The improvement consists of the novel and peculiar construction and combination of the parts, which will be hereinafter more"fully described and claimed, and which are shown in the annexed drawings, in which- Figure l is a perspective View of a machine embodying my invention; Fig. 2, a detail View, showing the adjustable standard.

The frame comprises the rearbeam A, front beam A', and oblique side bars a. The supporting-wheels C are mounted on spindles at the ends of the rearbeam A'. The crank-shaft B, journaled in suitable bearings on the front and the rear beams A and A', is projected at its front end and journaled in the crank-guard D, which is oval-shaped and secured at its rear side to the beam A. The boxing F, projected fromthe front side of the crank-guide, receives the vertically-adjustable foot or standard Gr, which is held in an adjusted position by a pin gvpassing through one of the series of openings g in the said standard and through a keeper f on the said boxing. The dog H is mounted at its inner end on a pin h, which passes through the sides of the boxing F, and is adjustable at its outer endto the log to be cut, being held rigidly by the bracebar h', which passes through a keeper h2 on the boxing, and a pin h3, that passes through the keeper h2, and one of a series of openings in the brace h. The dog I is connected by clip 'L' with the wheel-spindle, and is held in an elevated posit-ion by the holder i', which is secured to the beam A and overhangs the wheel.

The saw-guide frame .T comprises two side bars j j, which are mounted at theirinner ends on the axle B, and are united at their outer endsby the yoke j', to which is secured the lifting-rope K, the other end of the said rope passingrover a pulley k on the standard L, which projects up from the crank-guard D and down around the windlass K', which is held from turning back by the usual ratchet and pawl. One side of the standard extends to and is connected with the beam A, thereby bracing the crank-guard. p The saw M is secured to the front ends of two guide-arms N, which y"project rearwardly and pass through guide-,loops n and n on the side bars of the saw-guide frame J. The front ends of the guide-arms N are brought together and connected with the saw and with the crank b by the pitman O. .Y

The guide-frame J is braced laterally by the brace P. l

The operation of the invention can be readily understood from the foregoing description and the annexed drawings, and is as follows: .When transporting the machine on t-he field, the draft-power is applied to the clevis f2 on the boxing F, and the two dogs l-I and I are thrown up out of the way, as shown by' dotted lines. Motion is imparted to the crankaxle by horse-power or other suitableI motive power, the machine being steadied and braced by driving the pointed ends of the dogs in the log.

The front end of the machine is supported by the adjustable standard orfoot G, which can be lengthened or shortened to adapt the machine to the ground.

The crank-guard protects persons from injur Y y Having fully described my invention, what I claim, and desire to secure by Letters Patent, is-

l. The combination, with the frame, the saw, and the crank connected with thesaw, of the dog connected by clip, and the wheelspindle and the second dog connected by pin, with the front end of the frame and held in a nxed position by an adjustable brace, substantially as described.

2. The herein-described drag-saw, comprislIOO ing the frame mounted on Wheels, the crankshaft, the crank-guard secured to the front beam of the frame and having a boxing, the adjustable standard or foot passing through lhe said boxing, Ihe dog pivotally connected with said boxing and having an adjustable brace, Jche dog I, pivotall'y connected with the Wheel-spindle, the holder ,for supporting saidl dog I, the guide-frame having lateral brace and guide loops, the saw-guide arms passing through 111e guide-loops and connected by pitrnan with the said crank, and the Windlass connected with the said guide-frame, substantially as described.

In testimony whereof I affix my signature 15 in presence of two witnesses.
